The court filing says Harter made $408,919 in 2006; $414,545 in 2007; $262,964 in 2008; $262,466 in 2009; $177,066 in 2010 and $182,268 in 2011, and he willfully failed to pay income taxes on all of it.

According to Harter's attorney, Mark Schleben, Harter believed he was immune from paying taxes under Florida law.

Harter will likely argue that Harter didn't willfully break the law, he said.

"It is expected that prosecutors will also cooperate in preventing Dr. Harter's patients from needlessly suffering any disruption in their dental care, and preventing Dr. Harter's employees from suffering a sudden loss of their jobs," Schleben said in a statement.

In 2008, former Orlando resident, actor Wesley Snipes, was sentenced to prison in Ocala federal court after being found guilty of failing to file three years of tax returns on millions of dollars in income.

Each count carries a year in federal prison. If convicted, Harter could face a total of six years behind bars.
